Cross-Site Scripting vulnerabilities allow a third party to manipulate the content or behaviour of a web application in a user's browser, without compromising the underlying system.
Different Cross-Site Scripting related vulnerabilities are also classified under this category, including "script insertion" and "cross-site request forgery".
Cross-Site Scripting vulnerabilities are often used against specific users of a website to steal their credentials or to conduct spoofing attacks.
Positive Research has reported a vulnerability in Siemens SIMATIC WinCC, which can be exploited by malicious people to conduct cross-site request forgery attacks.
The application allows users to perform certain actions via HTTP requests without performing proper validity checks to verify the requests. This can be exploited to perform certain unspecified actions when a logged-in administrative user visits a specially crafted web page.
The vulnerability is reported in versions 7.0 SP3 and prior.
No official solution is currently available.
